To all whom it may concern;

Be it known that I, Gnonon L. BALLARD, a subject of the King of GreatBritain, and a resident of Norristown, in the county of Montgomery andState of Pennsylvania, have invented certain new and useful Improvementsin Knitting Machines, of which the following is a specification.

The invention relates to knitting ma- 7 chines and particularl to thetype of machine hav' that style of presser for-the needle bear s whichis ivotally supported at its lower end and stan s up in front of theneedle.

The invention is shown in the in drawings, in which:

igure 1 is a vertical sectional View of a part of a needle cylinder andsinker ring w1th my improved form of needle presser combined therewith.

Fig. 2 is a detail View of, the presser. Fig. 3 is a detail sectionalview of the sinker ring with the yarn guide mounted thereon.

accompany- Fig. 4 is a sectional view of the member slots 3 of thecylinder, these needles beingv operated in any suitable way as by thejacks 4. 5 indicates sinkers and 6 the ring or bed for the sinkers, andthese sinkers may be of the form which erforms the two-fold function ofsinking t e yarn and holding the web. My improved presser is shown at 7,this having a shoulder at 8 extending to the front of the main body ofthe presser and above its partly circular shaped lower end 9. This artlycircular lower end forms the pivot of t e presser upon which it rocks inits movement towards and from the needle during the pressing action andit will be observed that this partly circular lower end presents acurved surface at 10 which rojects beyond the substantially upstan ingedge 11 of the presser. This rounded surface 10 bears upon the needleshank while the shoulder 8 takes under a shoulder or rib 12 on presseris lan view,in the nature of a The yarn the inner face of the sinkerring. The pressor rests upon the led e 12 formed on the s nker rlnlgwhich the Mb 12 overhangs. The eld in place'by the formations justdescribed, the needle presenting by its shank a bearing surface for theinner side of the shoulder 8 under the rib 12. This construc tion avoidstheuse of the spring band which lower end of the presser which keeps theis ordinarily employed for holding the presser'm place. In order toremove any one of the pressers, it is simply necessary to remove thecorresponding needle and this will aflord sufficient-space to 7 permitthe lower end of the presser to be moved inwardly. towards theaxis ofthe machine so that the shoulder 8 may then be drawn out fromunder theoverhangin rib l2 and thereupon the presser may he raised and thus bewithdrawn from the machine.

The presser is not located in the needle slot, because the walls of theslot is cut away, at the region of the presser, excepting a smallprogecting portion at m at the verge of the cylinder to 'uide theneedles. Pressersin the. needle s 0t gives rise to considerable trouble,because a slight bend or un The yarn is fed to the needles through ayarn guide consisting of a plate 13 having a downwardly extendmg rib 14at its inner edge, this rib having a beveled face at 15. ide eye .16 isformed through this rib of t e plate and there may be a pluralit ofthese guide eyes as shown at 16 and 16, igs. 5 and 6. The rib 14 is ofcamshape as shown at 17, Fig. 6, and dotted lines Fig.5, this camformation tapering toward the left in Fig. 5, so that as the pressers 7come along in the direction of the arrow in said Fig. 5, they will belined u or moved outwar ly in res ect to the axis 0 the machine shou dany 0 these pressers have become dislodged slightl from their normalpositions. This wil cause the upper ends of the pressers to pass theguide eyes for the yarn without interference therewith.

A portion of the sinker wave is indicated at a: and a part of thepresser cam at .y.

I claim as my invention:

1. In a knitting machine having spring beard needles, a cylinder, a ringhaving. a ledge and a rib overhanging the same and 20 pressers 1n place,and cam means engaging spring beard needles, a cylinder, a series ofpressers, one for each needle, said pressers at their lower ends bearingupon the needle shanks, and ,on their outer ed es adjacent their lowerends, having shoul ers progecting beyond the said outer edges, a xed riboverlying the shoulders for holding the the upper portions of thepressers for operating them, substantially as descrlbed.

3. An individual presser fora sprmg beard needle comprising a memberterminating at its lower end in a rounded portion forming a pivotbearing portlon at said lower end, and a shoulder on its outer edgead'acent the rounded end ,to be engaged by holding means, the roundedportion extending beyond the outer and inner edges of the main part ofthe presser, substantially as described. c

4. In combination in a knitting machine, a series of spring beardneedles, a carrier therefor, a series of beard pressers pivotallsupported at their lower ends and upstan ing therefrom, a arn guide, andcam means for engaging an moving the upper ends of the beard pressersoutwardly to normal position to pass the yarn being fed, substantiallyas described.

5. In combination in a knitting machine, a series of springbeardneedles, a series of beard pressers individual to the needles pivotallysupported at their lower ends and upstanding therefrom, a yarn guideplate having a guideeye for directing the yarn to the needles and a.cam-shaped rib on the lower side of the yarn guide plate for engagingthe upper ends of the upstanding pressers to move the same outwardly tonormal 'connectin position to pass the yarn being fed to the needles,substantially as described.

6. A presser for spring beard needles having a lower edge face curved onthe arc of a circle of larger diameter than the width of the main partof the presser, said curved edge extending be 0nd the plane of both theinner and outer e ges of the said main part, and a shoulder at the frontof the presser the curved edge with the front edge of t e main part,substantially as described.

7. In combination spring beard needles, a presser having a rounded lowerenlargement with a shoulder on its outer side, a frame member having abearing for said rounded enlargement and a rib overhanging the same,said presser being retained in place the enlargement engaging the needleb sli ank on one side and the shoulder engaging the rib on the otherside, the removal of the needle permitting the disengagement of theshoulder from the rib and the removal of the presser, substantially asdescribed.

8. In a knitting machine and in combination, individual rocking pressersupstanding in front of the needles, a frame member havmg a rib engaginga portion of the presser near its lower part to hold the same in place,spring needles upon which the lower portions of the pressers bear to bethereby held in engagement with the rib, and cam means for engaging theupper portions of the pressers to rock them on their'lower portions, theremoval of the pressers being dependent on first removing thecorresponding needles, substantially as described.

9. In combination in a knitting machine, a cylinder, a ring surroundingthe cylinder, springbeard needles, a presser for each needle, each ofwhich has a rocking bearing upon a portion of the ring and also upon theneedle shank, said ring having a rib, the said pressers each having ashoulder to take under the .rib whereby the presserwill be held in placeby engaging the needle on one side and by its shoulder at its other sideengaging under the rib, the removal of the needle permittingdisengagement of the shoulder from the rib for the removal of thepresser.

In testimony whereof I afiix my signature.
